ITEMS NOT DELIVERED NOT CREDITED ON ACCOUNT

I placed an order at boardmans online on 16/01/2015, my account was billed with the full amount for the whole order. The items was only delivered on 03/02/2015. Some of the items was out of stock, and after confirming this with my telephonically, I was told a credit will be passed on my account within 3 days. After numerous calls to the call centre and emails, my account has not been credited with the amount for the items not delivered. So in effect, I paid for something I didn't receive. No one want to take responsibility and no one can actually confirm the credit. This is unacceptable. I want the credit on the account, and close the account. <br> Order number ***
